Universal LCD driver for low multiplex rates
7.10 Display RAM
The display RAM is a static 32 ? 4-bit RAM which stores LCD data. There is a one-to-one
correspondence between
? the bits in the RAM bitmap and the LCD elements
? the RAM columns and the segment outputs
? the RAM rows and the backplane outputs.
A logic 1 in the RAM bitmap indicates the on-state of the corresponding LCD element;
similarly, a logic 0 indicates the off-state.
The display RAM bit map Figure 11 shows the rows 0 to 3 which correspond with the
backplane outputs BP0 to BP3, and the columns 0 to 31 which correspond with the
segment outputs S0 to S31. In multiplexed LCD applications the segment data of the first,
second, third, and fourth row of the display RAM are time-multiplexed with BP0, BP1,
BP2, and BP3 respectively.

The display RAM bit map shows the direct relationship between the display RAM addresses and
the segment outputs and between the bits in a RAM word and the backplane outputs.
Fig 11. Display RAM bit map
When display data is transmitted to the PCF8562, the display bytes received are stored in
the display RAM in accordance with the selected LCD drive mode. The data is stored as it
arrives and depending on the current multiplex drive mode the bits are stored singularly, in
pairs, triples or quadruples. To illustrate the filling order, an example of a 7-segment
numeric display showing all drive modes is given in Figure 12 ; the RAM filling organization
depicted applies equally to other LCD types.
